The application of particle swarm optimization (PSO) to programming of pavement maintenance activities at the network level is demonstrated. The application of the PSO technique and its relevance to solve the programming problem in a pavement management system (PMS) are discussed. The robust and quick search capability of PSO enable it to effectively handle the highly constrained problem of pavement management activities programming, which has an extremely large solution space of astronomical...

Circular antenna array has gained immense popularity in the field of communications nowadays. It has proved to be a better alternative over other types of antenna array configuration due to its all-azimuth scan capability, and a beam pattern which can be kept invariant. This paper is basically concerned with the thinning of a large multiple concentric circular ring arrays of uniformly excited isotropic antennas based on Improved Particle Swarm Optimization (IPSO) method. In this paper a 9... Topics: Concentric Circular Antenna Arrays, Particle Swarm Optimization, Thinning, Sidelobe Level
In the deregulated electricity market, each generating company has to maximize its own profit by committing suitable generation schedule termed as profit based unit commitment (PBUC). This article proposes a Parallel Particle Swarm Optimization (PPSO) solution to the PBUC problem. This method has better convergence characteristics in obtaining optimum solution. The proposed approach uses a cluster of computers performing parallel operations in a distributed environment for obtaining the PBUC...

In this paper an attempt has been made to study the application of Thyristor Controlled Series Capacitor (TCSC) to mitigate small signal stability problem in addition to congestion management of a heavily loaded line in a multimachine power system. The Flexible AC Transmission System (FACTS) devices such as TCSC can be used to control the power flows in the network and can help in improvement of small signal stability aspect. It can also provide relief to congestion in the heavily loaded line.... Topics: Congestion management, Particle Swarm Optimization, Small Signal Stability, Thyristor Controlled...
Harmonic Elimination in a multilevel inverters is an optimization problem which is solved by applying particle swarm optimization (PSO) technique. The derived equation for the computation of total harmonic distortion (THD) of the output voltage of the multilevel inverter is used as the objective function in PSO algorithm. The objective function used is to reduce the THD of the multilevel inverter and obtain the corresponding switching angles with the elimination of possible lower order...
